Abstract

The invention relates to stabilized sodium carbonate peroxyhydrate (SCPH) particles having a coating layer comprising a mixture of lithium sulphate and sodium sulphate, said sulphates preferably being present in substantially equimolar amounts. The coated SCPH particles can be prepared by fluidized bed coating. The coated SCPH particles have good stability when used in detergents containing zeolites.
